That was, I believe a clear channel 50,000 watt station like WBAP
In the late 80’s just before all the clear channels went away I could listen to Texas Rangers Baseball games (On a good night) in our flat in the Mid-levels of Hong Kong. It was pretty amazing.
Internet streaming radio stations rock.
I now use a $30 Echo Dot on a small 2000 mAH battery outside and in the car.
(on some wifi AP/hotspot thingys)
WOW! You could get WBAP in Hong Kong? 50,000 watts went a long way! (Back then)
WBAP was the home of Bill Mack, who had a nightly show after midnight for the truckers.

But Bill Mack kept me awake many a night. Midnight Trucking Show.
That's damn good for the AM broadcast band! I once listened to WBAL (AM 1090) in Baltimore while parked in a rental car by the sea in Plymouth, England. That's a distance of 3500 miles. No doubt, being right by the water helped.
I've often heard WBZ (AM 1030) in Boston while visiting Chicago, especially when driving along the lake. It used to be routine to hear WLS in Boston at night, until they licensed a station in Dedham on the frequency. There are now 31 stations in the US and Canada on 890 (and 41 on 1030!). So much for clear channel.
Clear channel stations did not go away, the name just changed - https://en.m.wikipedia.org/wiki/Clear-channel_station
